A UK Royal Navy nuclear submarine, part of the Vanguard-class carrying Trident ballistic missiles and approximately 140 crew members, encountered a harrowing situation when a depth gauge malfunctioned during operations in the Atlantic.
The vessel, moments away from entering a critical depth "danger zone," faced the potential of disaster as the gauge falsely indicated a level position when, in reality, the submarine was still diving.
The critical incident unfolded as the submarine was gearing up for patrol duties.
When the depth gauge malfunctioned, indicating an incorrect level, engineers onboard noticed the discrepancy and immediately raised the alarm.
Although technically the submarine was within operational depth limits, the crew recognized the anomaly and intervened before reaching a point where the entire crew would have been summoned to action stations.
The situation underscores the precision required in submarine operations, especially when carrying nuclear weapons.
A Royal Navy spokesperson said; “Our submarines continue to meet their commitments, deploying globally on operations, protecting national interests, and keeping us and our allies safe.
"While we do not comment on specific details regarding submarine operations, safety of our personnel is always the highest priority."
